VEHICLE POSITION DETECTING APPARATUS
First Claim
1. A vehicle position detecting apparatus, comprising:
- a position measurement unit that measures a position of a first vehicle as an own vehicle to obtain first position information as position information of the first vehicle;
an autonomous sensor that detects a relative position, relative to the first vehicle, of a second vehicle to obtain relative position information of the second vehicle, the second vehicle being a vehicle different from the first vehicle;
a receiver that receives communication data obtained by the second vehicle and sent from the second vehicle, the communication data containing second position information as position information of the second vehicle;
an identification unit that performs identification on the second vehicle specified based on the relative position information and the second vehicle from which the communication data is sent, based on the first position information, the relative position information, and the second position information;
a position error calculator that calculates, for the second vehicle identified by the identification unit, a difference, as a position error, between a position of the second vehicle specified based on the relative position information and a position of the second vehicle specified based on the second position information; and
a position corrector that performs, based on the position error, a correction on the position of the second vehicle specified based on the second position information, on a condition that the second vehicle identified by the identification unit is no longer detected by the autonomous sensor.

Abstract
A vehicle position detecting apparatus includes: a position measurement unit that obtains first position information of a first vehicle; an autonomous sensor that obtains relative position information of a second vehicle; a receiver that receives communication data containing second position information of the second vehicle; an identification unit that performs identification on the second vehicle specified based on the relative position information and the second vehicle from which the communication data is sent; a position error calculator that calculates a position error between a position of the second vehicle specified based on the relative position information and that of the second vehicle specified based on the second position information; and a position corrector that performs, based on the position error, a correction on the position of the second vehicle specified based on the second position information, on a condition that the identified second vehicle is no longer detected by the autonomous sensor.
